I have Direct TV and a slimline dish when I camp. First I go to this website:
http://www.dishpointer.com/ Also, invest in a hand held compass with a pointer arrow so you can get a better feel for the direction of the dish.
Type in your zip code and then use the map to get to where you are. Depending on which satellite system you are using, locate the correct satellite to seek. With Direct TV the most common one is 101W.
This gives me the elevation and azimuth as well as a line of sight picture showing the neighborhood and possible building obstructions. You can drag the pointer to your exact location.
Go to your satellite set up menu and bring up the signal strength screen for 101W. You should see 32 places for reception. Each one allows for certain channels to come in. The more numbers you can get the more channels you'll receive.
If you have a pretty good azimuth setting, then slightly play with the elevation or vice versa. Once you see numbers starting to show up on your set up screen, just keep slightly moving the dish until you get the highest numbers. You will want 80s minimum but 100s come easily once you are on the beam. The more numbers you see the better the signal. If you want the HD now you need to go to those satellites 103b and play with the skew(rotation). SLOWLY move the dish until you get the best numbers.
IF your receiver beeps, the faster the beeps the better the numbers. If it doesn't, be prepared for an aerobic set up as you will have to keep going back and forth to your tv and dish depending on where you have them placed. A second person to just watch the tv helps greatly.
I know this sounds a little complicated but once you've done it a couple of times it isn't bad. You may also have to refresh your receiver if you've travelled a distance to Huntington, and you may have to call Direct TV and give them your location just for the temporary set up.
Charge on and GO HERD!!!
